English Name: D (+) -Tryptophan English Name: D-Tryptophan; (R) -2-Amino-3- (3-indolyl) propionic acid; H-D-Trp-OH CAS:153-94-6 Chemical formula: C11H12N202 Molecular formula: C11H12N2O2 The molecular weight of:204.23 Appearance: white crystalline powder Content is more than 99 (%) The melting point (266-8 ℃) Dry weight loss ≤ 0.2 (%) Heavy metals (ppm ≤ 10) Specification: 20kg/ bucket Application: pharmaceutical health care products Application: is the important nutrition agent, used medicinally to pellagra preventive agent; D- tryptophan as a non protein amino acids, has a special physiological properties, in the food and feed industry and agriculture can be used as a non nutritive sweeteners, feed additives, plant growth regulator, in the pharmaceutical industry, the main for the synthesis of various polypeptides, instead of L- tryptophan prolong the half-life of peptide drugs and reduce side effects, does not produce resistance and become an important precursor for the synthesis of enzyme inhibitors. Can enhance the body's immunity, delay the onset of allergic reaction. The majority of polypeptide antibiotic resistant gram positive bacteria, some of which gram negative bacteria such as Pseudomonas aeruginosa, mycobacteria, fungi, bacteria, virus and tumor cells have better inhibitory or killing effects. D- tryptophan synthesis of antibiotics, the side chain plays an important role for its pharmacological function, the peptide bond is hard to β - lactamase effect, which has high stability, and wide antimicrobial spectrum, low toxicity, allergic low, quick absorption, high blood concentration, duration. Long etc.. Purity :99% Price:USD146.7/kg
